Estado: Pendiente de análisisCrítica (9.8)—

An unauthenticated remote attacker can exploit an authentication bypass in the _account_log function to log in as an admin, even when accounts are properly configured.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector CVSS AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). El bypass de autenticación en _account_log permite acceso como admin (T1078), crear cuentas administrativas (T1098) y potencialmente ejecutar comandos (T1059).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
